Yes I was thinking the same thing, although I was hoping there was a more 
elegant mechanism exposed by the solr infrastructure code to handle the shared 
map, aside from just using a global that is.

I definitely haven't tried this ;=) but perhaps you could create your own 
XXXSynonymFilterFactory  as a subclass of SynonymFilterFactory,  which would 
allow you to share the synonym map across all cores - though I think there 
would need to be a nasty global variable to hold a reference to it...
